BRICK AND TILE KILN.

SPECIFICATION forming part of Letters Patent No. 517,883, dated April 10, 1894.

Application filed March 23, 1893. Serial No. 467,371. (No model.)

To all whom it may concern:

Be it known that I, GEORGE N. PHARES, a citizen of the United States, residing at Sheridan, in the county of Hamilton, State of Indiana, have invented certain new and useful Improvements in Brick and Tile Kilns, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in brick and tile kilns, and it has for its objects to provide a kiln which shall be cheap in construction, and in which increased draft is obtained and the brick and tile more quickly and evenly treated. I provide an arched fioor beneath which the fire is placed and above the said arches are provided air inlets which are alternately arranged upon opposite sides of the kiln. The said arches terminate in vertical fiues also alternately arranged upon opposite sides of the kilnand which extend for a considerable distance above the entrance to the outlet fiues from the kiln which latter are preferably arranged at diametrically opposite sides of the kiln and at right angles to the inlet fiues or tubes. By this means the heat is forced to pass upward through the brick or tile to nearly the top of the kiln and thence passes downward and out the outlet fiues near the bottom. Y

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure l is a horizontal section through my improved kiln, on the line 1--1 of Fig. 2. Fig. 2 is a vertical section of the same on the line 22 of Fig. 1. Fig. 3 is a detail in elevation.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the casing or surrounding wall of the kiln of any suitable material and capacity, preferably circular as shown and provided with a dome-shaped top A having an outlet 0. closed by a damper a as seen in Fig. 2.

terminate in or communicate with vertical fiues or semi-fiues D which extend up within the interior of the kiln to about one half or more of the height thereof as seen in Fig. 2. The outer walls of these fiues are formed by the inner wall of the kiln as seen in Fig. l. These vertical fiues also alternate as seen in Fig. 1. Above the arches are the air inlet openings 0 which alternate, that is, they are over the one arch upon one side of the kiln and over the next arch at the opposite side, as shown clearly in Fig. 1.

G are the stoke openings which are also consequently arranged alternately as will be readily understood.

E are the outlets which are located near the bottom of the kiln and extend at right angles to the arches as shown in Figs. 1 and 2. They extend horizontally outside of the wall of the kiln and then extend upward for any desired distance. The horizontal portions of these outlets should be near the bottom of the kiln and a considerable distance below the upper ends of the fiues D as shown in Fig. 2 so that the hot air will pass upward nearly to the top of the kiln and through the brick or tile before it descends to pass out through the said outlet pipes.

The brick or tile are designed to be supported upon the arches and will be piled within the kiln in the usual manner. They are not shown in the drawings.

In operation, the fire is made in the spaces beneath the arches and the products of combustion pass up through thev vertical fiues upon opposite sides of the kilnand through the brick or tile, air being admitted through the openings 0 and the hot air being forced to approach the top of the kiln before taking a downward course and out through the outlet pipes. Should the air in the kiln get too hot it may be regulated by means of the damper a at the top.

Importance is attached to the outlets E arranged at right angles to the length of the archesjoutside the kiln, whereby better draft is obtained and the bottom tier of tile is better burned and at less expense.

What I claim as new is 1. The herein described kiln consisting of the outer casing or surrounding wall with continuous curved arches forming a support for the tile or material to be burned above the bottom proper, the said arches being open at alternately opposite ends and terminating at their other ends in curved vertical fines the outer walls of which are formed by the side casing, and the Vertical outlets exterior of the kiln at right angles to the length of the arches and having horizontal portions communicating with the interior of the casing above the tops of the vertical portions of the arches and between the same and the upper ends of the Vertical fines, substantially as specified.

2. The herein described kiln consisting of the outer casing or Wall with dampered outlet in its dome-shaped top, the bottom formed upon the exterior with horizontal continuous arches, each arch being open at one end at the exterior of the casing and at its other end terminating in integral vertical fines extended above the outlet openings of the draft flues, the openings and vertical fines of said arches being alternately arranged and the vertical outlet fines exterior of the casing and having horizontal connecting portions communicating with the interior of the casing below the upper ends of the vertical flues and above the tops of the arches and arranged at right angles thereto and to said arches, all substantially as herein shown and described.

In testimony whereoflaflix my signature in presence oftwo witnesses.

GEORGE N PHARES.
